Question

所以我试图加入一个数组，所以我可以将字符串保存为csv。它工作但我得到额外的报价和列显示在csv文件中，我如何解决我的问题。

var arr = ["Merry, Christmas", "Halloween", "New Years", "other"]

var quotedAndCommaSeparated = "'" + arr.join("','") + "'";

将字符串保存到csv文件后，有2个问题。

有两个双引号，一个在csv的行的开头和结尾。数组中的第一个字符串也被分成2列，因为它有一个逗号。

Answer 1

CSV 文件格式不适用于单引号(')，您可以更改您的连接字符串，如下所示。

var arr = ["Merry, Christmas", "Halloween", "New Years", "other"]

var quotedAndCommaSeparated = '"' + arr.join('","') + '"';
console.log(quotedAndCommaSeparated);

Answer 2

根据spec for a CSV，您必须使用：

每个项目周围的双引号，如果它们可能包含双引号或逗号
通过＆＃34;倍增＆＃34;来逃避每个项目中的任何双引号双引号

＆＃13;

var arr = ["Merry, Christmas", "Halloween", "New Years", "Item with \"Double Quoted\" string"];

// Temporary array to store the modified entries in for the CSV
var arrDoubled = [];

// Loop over the original array, and double up the double quotes
// by taking each item in the `arr` array, and doing a global (`g`) replace
// to change all " to ""
arr.forEach(function(item) {
    arrDoubled.push(item.replace(/"/g, '""'));
});

// Use Double Quotes instead of single for the CSV
// Note that '"' is the same as "\"" (each is a string with a single double quote as contents)
var quotedAndCommaSeparated = "\"" + arrDoubled.join("\",\"") + "\"";

console.log(quotedAndCommaSeparated);
